Method and apparatus for adaptively managing cache pool

Abstract

Provided is a method for managing an adaptive cache pool, which is performed by one or more processors, and includes receiving monitoring information on a cache memory divided into a plurality of cache pools, and adjusting a cache region associated with at least one of the plurality of cache pools based on the monitoring information.

The invention claimed is: 
     
       1. A method for managing an adaptive cache pool, performed by a processor, the method comprising:
 receiving monitoring information on a cache memory divided into a plurality of cache pools; and 
 adjusting a cache region associated with at least one of the plurality of cache pools, based on the monitoring information, 
 wherein; 
 each cache pool of the plurality of cache pools is allocated to a different workload among a plurality of workloads; 
 each workload of the plurality of workloads is associated with a different data structure among a plurality of data structures; and 
 the adjusting comprises: 
 adjusting, based on the monitoring information, the cache region, for at least one of the plurality of workloads. 
 
     
     
       2. The method according to  claim 1 , wherein the monitoring information includes at least one of an access log to an address associated with each cache pool of the plurality of cache pools, or a cache hit-rate. 
     
     
       3. The method according to  claim 1 , wherein the adjusting the cache region comprises:
 determining a target cache pool to change the cache region, based on information on the plurality of workloads associated with the data structures; and 
 changing a main memory address associated with the determined target cache pool. 
 
     
     
       4. The method according to  claim 1 , wherein the adjusting the cache region comprises:
 determining a target cache pool to change the cache region, based on information on the plurality of workloads associated with the data structures; and 
 changing a cache memory capacity allocated to the determined target cache pool. 
 
     
     
       5. The method according to  claim 1 , wherein cache regions associated with the plurality of cache pools are adjusted such that different data structures are associated with different cache pools. 
     
     
       6. The method according to  claim 1 , wherein the monitoring information for the cache memory is received periodically or aperiodically, and
 cache regions associated with the plurality of cache pools are adjusted periodically or aperiodically using the received monitoring information. 
 
     
     
       7. The method according to  claim 1 , further comprising:
 prior to the receiving the monitoring information, 
 acquiring a type of an application requested to be executed; and 
 dividing the cache memory into the plurality of cache pools based on the type of the application. 
 
     
     
       8. A computer-readable non-transitory recording medium storing instructions for causing performance of the method according to  claim 1  on a computer hardware. 
     
     
       9. A computing device, comprising:
 a cache memory; and 
 a processor connected to the cache memory and configured to execute at least one computer readable program for controlling the cache memory, 
 wherein the at least one program includes instructions for: 
 receiving monitoring information on a cache memory divided into a plurality of cache pools; and 
 adjusting a cache region associated with at least one of the plurality of cache pools based on the monitoring information, and 
 wherein: 
 each cache pool of the plurality of cache pools is allocated to a different workload among a plurality of workloads; 
 each workload of the plurality of workloads is associated with a different data structure among a plurality of data structures; and 
 the adjusting comprises: 
 adjusting, based on the monitoring information, the cache region, for at least one of the plurality of workloads.
